Hot Pouch Laminators are the most popular type of laminator used to encapsulate a document within a pouch which has 2 connected sides in which the item to be laminated is positioned. The pouch is coated with a heat-activated film, which melts when passed through the heated rollers and is then bonded under pressure, removing all of the bubbles and creating a tight seal. Some basic differences to consider when choosing a laminator include: Rollers: Basic laminators have two rollers - high-volume laminator’s use 4 up to 10 rollers - the more rollers, the better the lamination Motor Speed: Higher-end pouch laminators have a variable speed to gives optimum throughput. Temperature Control: Basic laminators have a set temperature and higher-end laminators have an adjustable temperature controller for various types of lamination film. Width: Pouch laminators are available from about 4’’ wide for badge lamination to A1 size for posters and signs. Pouch Thickness: Laminators can handle different thicknesses of pouch from 150 micron to 500 micron total. Also consider features like auto reverse or release in case of a jam, photo quality, easy upright storage, carry handle, metal construction.
